CVE-2023-31304

Status: DeferredLow (2.3)—

Improper input validation in SMU may allow an attacker with privileges and a compromised physical function (PF)     to modify the PCIe® lane count and speed, potentially leading to a loss of availability.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
